I believe that arimi can be done EOD it has a life of 3 days.
I may be wrong let me look, the post on PCTS is good info its a sticky check it out that may answer your questions.
I was going to post something similiar, like using letro and nolva would everyday be wise at 2.5 letro and 30mg nolva or letro 2.5mg EOD and nolva ED?
I believe that taking nolva with it will not hurt and maybe even keep bloat down, clomid and nolva too at the end.
Its to early and its all so damn confusing..lol
